Expired minute volume (VE) is a measure of the amount of air that is exhaled from the lungs in one minute. It is calculated by multiplying the tidal volume (VT) by the respiratory rate (RR). The tidal volume is the volume of air that is moved in and out of the lungs during a single breath, while the respiratory rate is the number of breaths taken per minute.
Expired minute volume is an important parameter in respiratory physiology, as it reflects the efficiency of gas exchange between the lungs and the environment. It is influenced by a number of factors, including age, gender, body size, physical fitness, and lung health. For example, during exercise or in conditions such as asthma or chronic obstructive pulmonary disease (COPD), the respiratory rate and tidal volume may increase, leading to a higher expired minute volume.
Expired minute volume is measured using various methods, including spirometry, which involves breathing into a device that measures lung function. It is used to assess lung function and diagnose respiratory disorders, as well as to monitor the response to treatment. Normal values for expired minute volume depend on a variety of factors, but generally range from 5 to 8 liters per minute in healthy adults. Abnormal values may indicate a range of respiratory or cardiovascular disorders, and may require further testing or treatment.
